July 5, 2009 To All RADIO AMATEURS BID: $ANS-186.03
Many of the SuitSat-2 team members will converge on Phoenix during the weekend of July 10-12 for a system integration party. The team expects to put all of the hardware modules together that have been developed in many parts of the country. SuitSat-2 Project Manager, Gould WA4SXM said, "It is great to be at the point that we can start testing system operations with the hardware and software. The fun begins Friday July 10." You can keep up with the integration activ- ities next weekend using Twitter http://twitter.com/GGouldSmith.

SB SAT @ AMSAT $ANS-186.04 AO-51 Engineering Team Continues to Monitor Power Levels
AMSAT News Service Bulletin 186.04
From AMSAT HQ SILVER SPRING, MD.
July 5, 2009 To All RADIO AMATEURS BID: $ANS-186.04
Due to the increasing time AO-51 is spending in eclipse AMSAT Vice-President of Operations, Drew KO4MA reports that transmitter power levels have needed to be reduced. This way the batteries will provide enough power to keep the satellite operational when the solar cells are not providing charging current. AO-51 users have already noted the weaker signals on the downlinks.
The AO-51 Control Team Web Page for latest operating information will carry the latest status of the satellite. See: http://www.amsat.org/amsat-new/echo/CTNews.php
AMSAT now has a Twitter account at http://twitter.com/AMSAT where the AO-51 Operations Team will try to tweet things too small for ANS bull- etins or email, but of interest to the general AMSAT community. The most recent tweet reported, "AO-51 is in "normal" mode, telemetry on 435.150 @ 240mw, V/u repeater on 435.300 @ 290mw."
Gould, WA4SXM, AO-51 Ground Control Station said, "The eclipse time should start to decrease over the next few days hopefully allowing improvement in the transmitter power settings."
Gould continues with the news, "The AO-51 telemetry archive is up to date as of last night. AO-51 telemetry data is available in raw for- mat, CSA (comma separated variable) format that has the channel data converted by the configuration equations and there are some Excel files (most with graphs). There are a number of Excel files with graphs for June 2009 as that was a very interesting month for AO-51 operation. I encourage exploration of the data and any insights gleaned."
The telemetry archive can be found at: http://www.amsat.org/amsat/ftp/telemetry/ao51/

SB SAT @ AMSAT $ANS-186.06 Special Event Station 4C50C via Satellite From Mexico
AMSAT News Service Bulletin 186.06
From AMSAT HQ SILVER SPRING, MD.
July 5, 2009 To All RADIO AMATEURS BID: $ANS-186.06
Omar XE1AO, a regular satellite operator from central Mexico, reported news of a special callsign that will be showing up on the satellites between now and 31 August 2009.
The call, 4C50C ("Four Charlie Fifty Charlie"), is part of the "Trabaja Todo Colima" (Work All Colima) special event currently taking place in the central Mexican state of Colima. This event is commemorating the 50th anniversary of the creation of the J. Roberto Levy radio club in that state.
During the months of June, July, and August, stations from all over Colima have been on HF and the satellites, trying to put all 10 Colima "municipios" (municipalities, similar to counties in the USA) on the air. On HF, the special call XE50C has been used from different parts of Colima. Now, four hams (XE1AO, XE1ATZ, XE1AY, and XE1J) have been authorized by the Mexican telecommun- ications regulator CoFeTel to use 4C50C on the satellites as part of this event.
Initially, XE1AO will attempt to put 4C50C on AO-51's evening passes along with VO-52 and FO-29 evening passes. Omar and the other 3 hams hope to expand the use of 4C50C onto SO-50 and AO-27, plus look at passes at other times of the day during this period.
For hams outside Mexico, XE1J is the QSL manager for these special calls. The Mexican QSL bureau will take care of QSL requests from XE hams. Along with the QSL cards, there will be a certificate available to stations that work stations in at least 7 of the 10 Colima municipalities and also accumulate at least 74 points based on the location of the stations worked in Colima. Additional points are available for working certain stations like XE50C and 4C50C.

Seems I can't get a break from Murphy.
A couple of weeks ago, I received my azimuth rotor & G5400B control box back from Yaesu after the rotor had failed.
Yesterday I noticed the control box had turned off, and was generating a lot of heat. Sure enough, I checked the fuse, and it was blow. Opening up the case and looking for obvious problems, such as cold solder joints, burned components, etc., didn't show anything interesting; other than a hot transformer.
Unit blows fuses as soon as they are replaced.
So before I call up Yaesu and am off the air for another 2 or 3 weeks, any ideas from someone who perhaps has had the same problem? I had it connected to my LVB tracker, which no longer functions, as I believe it gets its power from the control box.

Hi Sebastian,
I had the same problem on my control box last week. Turns out there was a shorted turn in the transformer. Remove the cables to the rotator and LVB tracker and check you are getting the 11V and 26V AC out of the transformer. I just sent it down to one of the specialist companies the re-wind transformers in the area to fix it rather that going though the pain of sending it back to Yeasu for replacement.
Best Regards, Allan Saul ZS1LS
